I was trying to create two tap interfaces, attach it to a linux bridge, send frame via one tap interface and hoping to receive from the other tap interface.

I suggest you read up some degian networking concepts.

Well, you can create a tunnel! The first byte of the frame you read from the tap interface is the first byte of the destination MAC, and the other fields follow.

Wiresharks says that it has a “Bogus IP header length 0, must be at least 20 ” I believe it has something to do with. While it’s not strictly required, you may want to spend some more time configuring the nethead uml machine. Android unfortunately has support only for tun.

If you don’t see anything entering the tap interface, that’s probably the case. This script is provided below. In your specific example of tap1 and tap2, you could create a second routing table where traffic is routed out tap2, then mark ICMP traffic with iptables, and finally add a routing rule which uses the alternate routing table for marked packets.

It should definitely work, as long as always tun/twp the client connected to the TAP interface is able to reach the DHCP server and viceversa.
